7 * ncdecodex87.c - Handles x87 instructions.
8 *
9 * Note: These instructions are derived from tabler A-10 in Appendx
10 * section A.2.7 - x87 Encodings in AMD document 24594-Rev.3.14-September
11 * 2007, "AMD64 Architecture Programmer's manual Volume 3: General-Purpose
12 * and System Instructions".
13 *
14 * Note: This modeling code doesn't handle several aspects of floating point
15 * operations. This includes:
16 *
17 * 1) Doesn't model condition flags.
18 * 2) Doesn't model floating point stack adjustments.
19 * 3) Doesn't model all differences in size of pointed to memory ($Mf is used
20 * in such cases).
21 *
22 * Note: %st0 and %st1 have been inserted and made explicit, when necessary
23 * to match the disassembler xed.
